We had to convert the 8" can holes to 6" on our screened in porch to use Alexa controlled lighting. We did this since the fan was on the same switch and we didn't want to run a different wire. We ordered deep inserts so small onions don't sit in a big hole. However, since we had vinyl, we had a 1" discolored ring around the rim of all three cans. We ordered the same diameter rings as the original 7.5" OD and 6" ID. They are perfect. One photo.
